Regarding the interview with SF, I have to say that the geographical location of the company is quite biased. I have been to many development zones, but the transportation of this company is the most inconvenient. The traffic in Changzhou is very convenient. Whether it is train, bus or city bus, the city is clean and tidy, but the bus to Shunfeng Optoelectronics is not smooth. When you took the 74- 1 to transfer to the company, the bus waited 1 hour. Secondly, about travel expenses reimbursement? Compared with the interview of Japanese companies (whether the interview is successful or not, most domestic companies will not reimburse the travel expenses in advance), because the idea of most domestic business people is: I will give you an interview opportunity, and if you succeed, it will be equivalent to giving you a job, but if you fail, you will have to pay a certain price for finding a job. Under the traditional culture of China, most job seekers are in a humble state. Thirdly, regarding the interview, I have to say that the interview with the same industry is abnormal. The interview starts at 1: 00 p.m., with a small technician, four-to-one interview (one human resource with three senior technicians), and the interviewer lasts at least 40 minutes per minute. I was the third interviewer, and I waited there for 1 hour for 40 minutes, which made me miss the bus back at night. For the technician interview, of course, there are also speechless questions. I remember the menopausal aunt with long hair and eyes. For me who majored in microelectronics and worked in diffusion for one year, the first question is actually the principle of solar cell power generation. This is like asking a first-year student 1+ 1 what is it? I said impatiently, and as a result, he kept asking this question, as if she knew the photovoltaic effect very well, as if she knew the specific trajectory of photovoltaic carriers in the PN junction.
I finally finished the interview in 20 minutes in an impatient situation. The following questions were raised:
professional knowledge
1. principle of solar cell power generation
When answering this question, I despised this kind of question so much that I offended my menopausal aunt and asked me why.
2. What are the daily process anomalies of diffusion? Mainly the process part?
Let me say a lot. In fact, all technological problems are basically caused by equipment. It seems that he doesn't know much about TEMPRESS, but his aunt knows a lot about X.
3. What are the diffusion furnaces? Structure of diffusion furnace
I talked about TEMPRESS, but my aunt seems to know more about CT, which means I'm an amateur.
4. What are the steps in the diffusion process? What happened to your diffuser?
The front is a small case problem, but the back is more than two. Fatigue is the responsibility of the periphery.
5. What effect does diffusion have on various electrical performance parameters?
Personally, I think this is a very good question, which is typical, because some craftsmen who work in the former road generally don't care too much about this.
6. Why do you want to do high square resistance?
In small cases, that is to say, when the short flow increases, the opening pressure will decrease in theory, but it will increase in practice. Why is this? There are many reasons behind this. ......
7. Why does the resistance of the block increase? What are the components of PS resistor?
As for the composition of resistance, I said it is mainly junction resistance and positive contact resistance. He kept asking me. What else is there? I was stunned. I didn't react at the time. Later, I thought that I might forget to mention the resistance of the material itself (the back field of the silver paste silicon wafer). This question is not answered well.
Other questions: Why did you leave your job or something ... Blow it.
About the treatment: there is no bonus for the internship period of 3 months, and there are only more than 2,000 technicians or assistants, and more than 4,000 after becoming a full member.
Tip: the workshop is poisonous, and you will make less money in your life!
